Installation Manual
WARNING:
Never touch the terminals of the inverter
directly. It will cause lethal electric shock.
WARNING:
The final connection for DC strings should be
done at the array not at the inverter.
WARNING:
Because this inverter is non-isolated, only
two types of PV modules are acceptable: monocrystalline
and poly crystalline with only Class A-rated. To avoid
any malfunction, do not connect any PV modules with
possibility of leakage current to the inverter. For example,
non-grounded PV modules will cause leakage current to the
inverter.
CAUTION:
To reduce the risk of injury, use the proper cable
size for PV module connection.
CAUTION:
To reduce the risk of damage due to surge,
Electriq Power recommends surge protection between the
modules and the inverter.
Note on DC Wiring and NEC
Some electricians or installers may be unfamiliar with DC wiring in a
residential setting. Make note of all relevant codes, which may include:
1. NEC 690.31(G) for DC PV circuits in buildings.
2. NEC 215.12(C)(2) for correct DC wiring coloring.
3. NEC TABLE 310.15(B)(16) for Allowable Ampacities of Insulated
Conductors for Not More Than Three Current- Carrying Conductors in
Raceway (conduit wiring over 12").
4. NEC TABLE 310.15(B)(17) for Allowable Ampacities of Insulated
Conductors in Free Air (chassis wiring).
Rapid Shutdown
Electriq Power Systems are compatible with NEP devices to comply
with NEC 2017, and Tigo rapid shutdown devices to comply with
NEC 2020 regulations. Tigo TS4-A-F and TS4-A-2F are examples of
compatible devices.
